A brief description of the Boukensha Ni Naritai To Miyako Ni Deteitta Musume Ga S Rank Ni Natteta manga:
The main character is an adventurer who prefers to spend time on dangerous journeys rather than sit in four walls and grieve. One of these adventures ended quite sadly, and a 30-year-old man returned home without a leg…
Now his goal is to help people and fight magic. He has a good knowledge of herbs, and often goes to the forest to collect potions. One day, his fate led to a crunch in the middle of the forest. A little girl was wrapped in a blanket. The hero could not leave the child and took her to the village.
The girl grew up and her father began teaching her how to handle a sword. The adopted daughter turned out to be a capable student, and soon the father gave her to the Guild.
Now the 10-year-old adventurer has received an S-rank, but for some reason she is in no hurry to return home. The man missed his treasure very much… When will they see each other again?
